HINGE.

SPECIFICATION forming part of Letters Patent No. 586,66 3, dated July20, 1897.

Application filed June 18, 1896.

T0 aZZ whom it may concern.-

Be it known that I, RICHARD W. HUBBARD, of Ashtabula, in the county ofAshtabula and State of Ohio, have invented certain new and usefulImprovements in Hinges; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in hinges, and more particularlyto that class known as door and gate hinges, the object being to providea simple, cheap, attractive, and durable hinge adapted to be secured inposition without the use of screws, whereby the cost and time necessaryin hanging doors, gates, and the like is greatly reduced.

'With this end in view my invention consists in certain novel featuresof construction and combinations of parts, as will be hereinafter morefully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a View of myimprovement. Fig. 2 is a view in horizontal section, showing the methodof securing the hinge in place. Fig. 3 is a detached view, and Fig. 4 isa view of the centering-plate.

A represents the connecting-sections or knuckles of my improved hinge,and 1 the connecting-pin by means of which said sec tions or knucklesare pivotally secured together. Each of said sections or knuckles isprovided on its outer face with a projection 2, having a flatbearing-surface 3, which latter is adapted to rest squarely in contactwith the outer face of the door and door-jamb, to which the hinge issecured, while the inner abutting faces of said sections are flat. Projectin g outwardly from each of said bearingsnrfaces 3 is a shank a, theflat face of which being a continuation of the flat surface of theadjacent connection or knuckle. The surfaces of shanks 4: are providedwith one or more barbed fins 5 and a number of barbs disposed in rows,said barbed fins and barbs running lengthwise said shanks.

As indicated in Fig. 2, the shanks 4 at are bent outwardly a trifle at apoint adjacent to the pin 1, so that while their inner or flat surfacesare parallel when the hinge and door to Serial No. 596,985. (Nomodel-lwhich it is secured are closed at the same time a narrow spaceintervenes between them. The object of this construction is to preventthe door from binding on the doorjamb, or vice versa, which so oftenresults from swelling or shrinking of the parts or in consequence ofpainting.

B is a centering-plate adapted to be placed between the shanks of thehinge, where it just fits, when the hinge is driven into the hole formedto receive it in the door and doorjamb.

Each section or knuckle is provided with a stop 6, adapted to limit theoutward movement of the article to which the movable section is attachedwhen said article is opened or moved sufficiently to bring said stops incontact with one another.

To apply hinges of the construction above set forth, it is firstnecessary to determine at what points on the door and door-jamb,respectively, the hole or recess for the reception of the shanks at isto be bored. Then this has been determined, the recess or hole is formedby centering the point of the bit in the crack between the door anddoor-jamb and boring the hole or recess so that one half of the borewill be in the door and the remaining half in the door-jamb. Thediameter of the hole thus made should be equal to the diameter of theshanks i when in their closed posit-ion. Before the hinge is secured inits operative position centering-plate Bis placed between shanks at andthe latter closed upon said plate, after which said shanks are placed ina position to be driven in the hole above referred to, which operationis accomplished by means of striking the hinge on the knuckles with ahammer or other instrument. During the passage of said shanks into theirrespective semicircular holes or recesses formed in the door anddoor-jamb, respectively, plate B follows the crack between said door anddoor-jamb and forces the shanks to adjustthemselves into theirrespective holes or recesses, leaving the fiat faces thereof flush withthe abutting faces of the door and door-jamb when the door isin a closedposition. \Vhen the shanks 4 are being forced to the'position abovedescribed, the barbed fins and rows of barbs enter the wood surroundingthe semicircular recesses and lock said shanks against accidentalremoval. The pointed or sharpened ends of said barbed fins and rows ofbarbs are inclined outwardly or in a direction opposite to that taken bythe shanks when driven into their operative position,and hence it willbe apparent that whenever strain or a pulling force is exerted on thehinges said barbed fins and rows of barbs will engage and embedthemselves firmly within the wood surrounding their respective socketsand prevent the hinge from being withdrawn from its operative position.The projections or lips 2, which firmly bear on the door and doorjamb,will also assist in preventing the accidental withdrawal of the shanks4. It is apparent from the foregoing that but little labor is necessaryto hang a door with my improved hinges and, further, the employment ofscrews is dispensed with, thus materially reducing the cost in materialas well as for labor.

It is evident that changes in the construction and relative arrangementof the several parts might be made without departing from the spirit ofmy invention, and hence I would IHHB it understood that I do notrestrict myself to the particular construction and arran gem ent ofparts shown and described; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A hinge comprising two sections or members the shanks of which havefiat inner faces, said shanks bent outwardly so that they lie paralleland slightly placed apart when the hinge is closed, the shanks providedwith finshaped toothed projections on their upper and lower edges, saidfins inclining slightly outward and their teeth extending inward fromthe end of the shank.

2. The combination with a hinge, the sections of which are provided witha shank, of a centering-plate adapted to be temporarily interposedbetween said shanks,substantially as and for the purpose described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
